Setting up Thermistor Inputs
The FMS-1650 includes two (2) dedicated thermistor inputs for
measuring and monitoring resistive temperature sensors, or
thermistors. These inputs may be configured for use with negative
temperature coefficient (NTC) Type 2 or Type 3 thermistors from BAPI®
or other manufacturers.
BAPI® manufactures several combination temperature and
humidity sensor products which are ideal for use with the FMS-
1650 for complete room monitoring and control applications.
Triatek recommends BAPI® part no. BA/10K-2-H200-R, which is a
combination temperature and humidity sensor includes a NTC Type 2
thermistor for temperature sensing and a ±2% humidity transmitter with
a 0 to 10V output.
Selecting Thermistor Input 1 or Thermistor Input 2 on the second page
of the Analog Inputs Setup menu invokes the Thermistor x Settings
configuration screen as shown in Figure 50. From this configuration
popup, the user may specify which type of NTC thermistor device
is connected and the engineering units for displaying the monitored
temperature on the main screen. If the thermistor input is being
utilized as part of a temperature control scheme, then clicking the
Next button at the Thermistor x Settings popup invokes the setpoint
entry configuration screen shown in Figure 49 where the user may
enter a target temperature setpoint. The thermistor input must also be
mapped to one of the analog outputs that has been configured for PID
control mode.
Figure 47. In lieu of
using a thermistor
input, a secondary
analog input may
be configured for
temperature sensors
which output a voltage
or current.
